IntraLase & Blade-free Laser Eye Surgery Technology

How does Intralase work?

The creation of the corneal flap prepares the eye for the second step of the LASIK procedure, when another laser, known as an excimer laser, is used to correct vision.

Unlike other procedures, the IntraLase Method creates the corneal flap by applying tiny, rapid pulses of laser light – not a metal blade (microkeratome). Each pulse of light passes through the top layers of your cornea and forms a microscopic bubble at a specific depth and position within your eye that is determined by the doctor. As the IntraLase or iFS Laser moves back and forth across your eye, a uniform layer of bubbles forms just below the corneal surface. Your doctor creates your corneal flap by gently separating the tissue where these bubbles have formed.

Because of the way in which the IntraLase Method creates a precisely positioned layer of bubbles just beneath the surface of your eye, it creates a smooth, even surface after your flap is lifted. The flap is then folded back so the doctor can perform the second step of your LASIK procedure.

The IntraLase Method flap creation process takes less than 15 seconds per eye. Including preparation time, the entire LASIK procedure typically takes about 10 minutes. Once the entire procedure is completed, the corneal flap “locks” back into position.

Intralase is what makes Laser Eye Surgery really metal blade free

Intralase has revolutionised Laser surgery by making the creation of the flap even safer and, consequently, has improved the precision, recovery time and the quality of vision achieved.

Intralase laser is a femtosecond laser that uses tiny, rapid pulses of harmless light to create a corneal flap, instead of using a blade. Each pulse of light passes through the top layers of the cornea and forms a microscopic bubble at a specific depth and position within the eye that is determined by the personalized treatment plan.

The Intralase laser moves back and forth across the eye, creating a uniform layer of bubbles of carbon dioxide and water vapour. These bubbles are precisely positioned to define the flap’s dimensions and hinge location. These bubbles expand to push the cells apart allowing the flap to be gently lifted and rested.

Intralase is able to create extremely precise corneal flaps that are stronger and thinner which consequently boosts the recovery time.

The corneal flap creation only takes 15 to 20 seconds. Once complete the flap can then be gently lifted and easily separated where these bubbles have formed to expose the area of the cornea that will be treated.
